way before Trudeau was found out I had a brief facebook discussion with Trudeau and the gap is his traditional 7 1/8" flipper post to flipper post as all his dmd games are.
people keep saying it is documented but this has never been proven, Stern never admit to mistakes so I for one don't believe it is documented just like the spelling mistake, pooling playfields etc.
what makes the gap seem bigger is the initial 6 months the flippers were set lower so you couldn't cradle and the flippers were lifted a little after about the 6 month mark. Also the initial 6 months had the outlane guides too low so people were getting alot of lane hop
